Problems solved by technology
The original installation method is to directly install the speaker outside the cabin. During the use of this device, the following defects were found: the sound transmitted was extremely weak, which made it impossible for the staff outside the cabin to communicate with the patients in the cabin. Communication, and thus very likely to cause the danger of medical malpractice

The invention discloses a pressure-bearing sealing sound transmission device for an oxygen cabin. The oxygen pressurizing cabin comprises an oxygen pressurizing cabin body, the sound transmission device comprises a penetration cabin pressure-bearing mounting seat, a sound transmission film sheet, a penetration cabin pressure-bearing mounting seat gland, a loudspeaker fixing mounting seat, a bolt,a screw and a loudspeaker. the cross-cabin pressure-bearing mounting seat is mounted in the oxygen pressurizing cabin body; the outer side of the penetration cabin pressure-bearing mounting seat is sequentially connected with a sound transmission film sheet and a penetration cabin pressure-bearing mounting seat gland through bolts, the loudspeaker fixing mounting seat is fixedly mounted in the penetration cabin pressure-bearing mounting seat gland, and the loudspeaker is connected with the loudspeaker fixing mounting seat through screws. By the adoption of the sound transmission device, electric equipment of the oxygen pressurizing oxygen cabin can be effectively isolated, the voice effect of the transmission horn can be guaranteed, the use safety of the oxygen pressurizing oxygen cabin can be guaranteed, and the sound transmission device has the advantages of being simple in structure, convenient to operate and use, low in cost, high in practicability and particularly suitable for application and popularization.
Description
technical field [0001] The invention relates to the technical field of oxygen inhalation devices, in particular to a pressure-sealed sound-transmitting device for an oxygen chamber. Background technique [0002] As we all know, the oxygen pressurized cabin is to place the patient in the cabin, and use oxygen to establish a treatment environment with a pressure higher than one atmospheric pressure, and the patient is treated under this pressure by directly breathing the oxygen in the environment in the cabin. Patients treated in the cabin need to maintain dialogue and communication with the outside world, so as to understand the treatment status in the cabin and guide patients to perform correct operations and deal with related matters. In order to achieve the above-mentioned purpose, the existing oxygen pressurized cabin is equipped with an intercom system in the cabin. Since the intercom system belongs to electrical properties, it is used in an oxygen environment, and there...
